如何在使用Swift和Xcode制作的SpriteKit游戏中创建主菜单？

Question

我使用SpriteKit和Swift在Xcode中创建了一个非常简单的游戏。现在我想要创建一个主菜单，以便当游戏打开时，会有一些按钮进入设置或开始游戏。但我不知道该如何实现。我应该使用故事板吗？如果是这样，我该如何在Xcode中实现它。谢谢大家 :)

可能是Swift中的主菜单的重复问题。 - SumNeuron

Swift 3.0

import SpriteKit

class MenuScene: SKScene {

    var playButton = SKSpriteNode()
    let playButtonTex = SKTexture(imageNamed: "play")

    override func didMove(to view: SKView) {

        playButton = SKSpriteNode(texture: playButtonTex)
        playButton.position = CGPoint(x: frame.midX, y: frame.midY)
        self.addChild(playButton)
    }

    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        if let touch = touches.first {
            let pos = touch.location(in: self)
            let node = self.atPoint(pos)

            if node == playButton {
                if let view = view {
                    let transition:SKTransition = SKTransition.fade(withDuration: 1)
                    let scene:SKScene = GameScene(size: self.size)
                    self.view?.presentScene(scene, transition: transition)
                }
            }
        }
    }
}

我该如何显示.sks文件并向其类发送一些参数？ - Arti

创建两个新文件。一个是Sprite Kit场景，一个是Cocoa Touch文件。它们的名称应相同，例如MenuScene。要创建这些文件，您需要在Xcode项目的侧边栏中单击文件夹。然后，为了让MenuScene在运行应用程序时显示出来，请进入GameViewController文件。在viewDidLoad下方有一行代码。if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {将其更改为if let scene = MenuScene.unarchiveFromFile("MenuScene") as? Menu Scene { 然后，在您的MenuScene中，必须有一个按钮，指向GameScene。

import SpriteKit

class MenuScene: SKScene {

var playButton = SKSpriteNode()
let playButtonTex = SKTexture(imageNamed: "play")

override func didMoveToView(view: SKView) {

    playButton = SKSpriteNode(texture: playButtonTex)
    playButton.position = CGPointMake(frame.MidX, frame.midY)
    self.addChild(playButton)


override func touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {


    if let touch = touches.first as? UITouch {
        let pos = touch.locationInNode(self)
        let node = self.nodeAtPoint(pos)

        if node == playButton {
            if let view = view {
                let scene = GameScene.unarchiveFromFile("GameScene") as! GameScene
                scene.scaleMode = SKSceneScaleMode.AspectFill
                view.presentScene(scene)   
            }   
        }   
    }       
}

如果您需要进一步解释，请提出询问。

嗨Miles，我在我的GameViewController文件中找不到if let scene = GameScene.unarchiveFromFile("GameScene") as? GameScene {这段代码。它在其他地方吗？ - King_Cui
